Fiserv Configuration Specialist

ITTConnect is seeking a Fiserv Configuration Specialist for a direct-hire full time position with a client in Miami.

Hands-on configuration role responsible for the deposits and ledger backbone of the bank in Fiserv Finxact. The specialist owns the product factory end to end — account types, positions, sub-ledgers, GL mapping, interest and fee logic, statements and posting rules — converting business and regulatory requirements directly into live, tested configuration rather than handing specifications to someone else to implement.

This is the anchor position of the core squad and the functional-technical reference point for integrations, digital channels, data and regulatory reporting. It operates in a managed-SaaS model where the vendor runs the platform and the bank owns configuration, so the value of the role sits in parameterization depth and accountability for what is actually live in production.

Key Responsibilities:

• Configure the Finxact product factory — account types (DDA, savings, CD), positions, sub-ledgers and GL mapping for the U.S. MVP scope.
• Parameterize posting rules, cut-off cycles and accruals; partner with Finance on chart of accounts, GL reconciliation and month-end close.
• Configure interest accrual and capitalization, tiered and promotional rates, fee schedules, waivers and statement generation.
• Translate business and regulatory requirements into configuration specifications with full traceability for examiner review.
• Build, test and document configuration across DEV/UAT/PROD under the bank's change-management and segregation-of-duties standards.
• Support UAT, defect triage, data conversion validation, dress rehearsals and go-live readiness for the deposits domain.
• Act as the bank-side counterpart to Fiserv implementation teams on deposits scope — backlog, platform limitations, roadmap and escalations.
• Serve as the deposits and ledger functional-technical reference for integrations, digital channels, data and regulatory reporting.
• Maintain configuration documentation, versioning and controls evidence for internal audit, external audit and examiners.

Requirements

• 10+ years of experience
• MUST HAVE experience with Fiserv platform, preferably with Finxact.
• 5+ years in core banking, including hands-on configuration within the Fiserv ecosystem — Finxact, DNA, Signature, Premier, Precision, Cleartouch or CoreAdvance. Configuration experience, not requirements documentation.
• Strong command of U.S. deposit products, general ledger mechanics, and interest and fee logic.
• At least one product personally configured end to end, from specification through production.
• Working knowledge of REST APIs, JSON and data mapping — sufficient to configure and troubleshoot an API-first core.
• Experience in a regulated, audit-driven environment with formal change management and segregation of duties.

Preferred

• Hands-on Finxact experience, Finxact Academy badges or Fiserv product certification.
• Core conversion or migration experience — data mapping, balancing, parallel runs.
• Call Report / regulatory reporting and finance-GL reconciliation integration exposure.
• AWS, Snowflake and MuleSoft familiarity
